DISCHARGE-VALVE MECHANISM. y

it is to be understood 'that the inventionis.

not limited to the exact details ofconstruction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art. i

In said drawings: f

Fig. 1 yis a vertical longitudinal section of a car tank 'equipped with my limproved valve mechanism, thevalve cage being shown partly in elevation; v

Fig. 2 is a section taken on line 2.-"2 of Fig. 1 showing the valve sleeve in theposition taken during the closing of the valve;

` Fig. 3 is a section taken on line 3 3 of Fig. 1 s howvingthe valve-sleeve in the posil tion taken during the opening of the valve;

Fig. 4 is a section 'taken on line 4--4 of Fig. 3 showing the valve in open position; Fig. 5 is a section taken on line 5-5 of Fig. 2 showing the valve in `engagement with its'seat; and v f y Fig.v 6l is a fragmentary view, partly in tsection. and partly in elevation, orf-the valve cage with a retaining ring secured thereto'.

' It is an object of my invention to provide an improved discharge valve mechanism for tank cars and it is also an object of myinvention to'provi'de a valve-structure of the self grinding type wherein the valve mayJ be lifted out of the cage for inspection with- "out removing the valve cage from the tank. In the drawings which show the preferred construction of my device the cars` tank 1.

l has the usual dome 2 provided-with ademe head 3 in which is the usual manholeopening closed by a cover 4. Secured to the dome 2 is a bracket 5 in which a valve rod,

6 provided with a handwheel 7 is rotatably mounted.\ Riveted to a bottom tank sheet is a discharge outlet casting'S provided at Application led l:Tune 2,'

192e. serial No. 565,484.

o'ne endwit-han outlet cap 9 having an open- 55 iig tlhoat. is closed by a screw threaded ,y

p ug I At its kother end the outlet easting'S is interiorly threaded to receivef a valve cage 11. 'Ihe valve cage llisprolvided withaa 60 valve seat 12 to receive a valve 13 having a cylindrical threaded stem 14 in which is a square opening to receive the squared end 15 vof the valve \ro`d 6. Threaded on the valve steml 14 isa valve sleeve 17 having' 65 i -the-A lugs 18, 19 and 20. In assembling the device, the sleeve 17 is threaded on to the stem 14 and the valve 13 and sleeve 17 are s' inserted through the opening in the top of the valve cage 11, openings 21, 22 and 23l 70 being provided in the flange 24 of thevalve cage 11 to permit the passage of the lu s `18, 19 and 20. The end-15 of the rod 6 1s? then fittedinto the opening in the stem 14.

With the valve 13 engaging the seat-12, 75

as shown infFig. ,1, operating the hand wheel 7 to open the valve will cause the valve 13 to rotate upon the seat 12 earryingthe sleeve 17 with it until the lugs 18 and 19 engage the faces 25 and 26 formed on-the valve`80 cage 11. With the sleeve 17 thus held against rotation, continuedo-peration of the hand wheel 7 rotates the valve .13 on the seat 12 and causes the sleeve 17 yto travel in the cage 11 until the lugs 18, 19 and 2O enl5 `gage the shoulder 27 (Figs. 1 and 4), whereupon continued rotation of the hand wheel will cause the valve 13 to be raised from the seat 12 (as shown in Fig. 4.). With the valve in the open position operating the hand wheel to close the valve will cause the valve 13 to rotate carrying with the sleeve 17 and causing the lugs 18, 19 and 20 to ,e travel on the shoulder 27 (Figs.- 1 and 4) until the lugs 18 and 2O engagel the faces 28 05 an'd 29` as shown in Fig. 2 whereupon the sleeve 17 will stop rotating and the valve 13 will advance in the sleeve 17 until it engages the seat 12 as shown in Fig. 5. Continued rotation of the hand wheel 7 will then cause 100 the valve 13 to rotate on theseat 12, inding the valve to its seat, 'and will cause the\ sleeve 17 to travel in the cagell until `the .lugs 18, 19 and 2O engage beneath the flange vilange'24` by meansoa ring 33 secured to the flange 24 by screws34.

To remove the valve 13 from the cage 11, the valve 13 is operated to the open posi tionas shown vin Fig. 4,!wherein the lugs 18, 19 and 20I aline with the. openings 21, 22 and 23 in the flange 24 of the cage 11, the valve rod 6 givith`drawn andthe ring 33 re" moved, if applied, whereupon the sleeve 17 A and valve 13l can be lited from the cage 11.

Integral with the cage 11 is aflug 30 provided with a plurality of openings so spaced that a set screw 31 threaded into one of the openings and .securedj by locknut 32 will engage with the head of one of the-rivets that securethe outlet casting 8 to the tank and prevent the cage 11 'fromgbeing un screwed from the outlet casting What I claim is: D
